WILLIAM ST. HILAIRE, OF LYNN, MASSACHUSETTS, ASSIGNOR O F ONE-HALF TO ALMER B. JERNIGAN, OF SAME PLACE.

MACHINE FOR SHAPING HEEL-STIFFENERS.

SPECIFICATION forming part of Letters Patent No. 240,561, dated April 26, 1881.

Application filed March 3, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM ST. HILAIRE,

a citizen of the United States, residing atLynn,

in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Shaping Heel- Stiffeners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. I 5 This invention relates to machines for shaping heel-stift'eners; and it consists in the construction and combination of parts hereinafter set forth and claimed.

In the accompanying drawings, Figurel represents a perspective view of a machine embodying my invention. bottom view of the same, omitting the lower portions. Fig. 3 represents a longitudinal vertical section through the middle of the same, and Figs. 4 and 5 represent detail views.

Adesignates the frame of my machine, which is. provided with a table, A, and at one end a vertically-slotted guide-standard, A reaching from the base of the frame to said table. In this guide-frame and through said table works a vertical plunger, 13, which is beveled at both ends. Its lower end, b, receives upward motion from a cam, 0, carried by the drivingshaft, and its upper end, I), bears against the similarly-beveled outer endof the shank d of a former, D, thus giving horizontal forward motion to said shank in suitable guides and moving the body of the former over the cen' tral opening of the table. When said former strikes against and forces backward the middle part of the matrix E, consisting of curved jaws e e, hinged together at s and having reversely-curved tails e 6, these tails impinge upon the sides of a triangular intermediate guide-block, F, which causes the front part of said matrix to close around said former. A guide-plate, Gr, secured to or formed with the top of said guide-block, and extending beyond its sides and point, prevents the said jaws from being displaced in an upward direction. As

Fig. 2 represents a.

the said cam passes from under the said plunger this plunger is retracted byspring h, the former D by spring h, and the matrix by spring h The guide-block F is held to its place by a strong spring, H, which is preferably wound round a shank or rod attached to said block and set within a slot of table A. This spring keeps the block motionless under all ordinary pressure, but will yield sufficiently to prevent refractory material from being injured when its thickness causes extraordinary strain.

The former D is provided with two springpressed yielding pins, I, which protrude through its sides and on which the blank is supported as the said former moves forward. The matrix, in closing on said former, forces in said pins, which are thrown out again by springs t when the former withdraws from the matrix.

The forward ends of the matrix-jaws c ehave 7o pivotal connection with two crimping-jaws, J J, which are sickle-shaped and provided in their straight portions with guide-slots jj, that enable them to slide longitudinally over fixed guide-studs J J. The closing of said matrix causes the curved and sharp-edged parts of said crimping-jaws to close upon the portions of the counter protruding above the top of the former and to fold them over the same tightly, thereby crimping them. These crimping-jaws So do not reach the remotest part of the counter, which is next to the forward end of the former. Hence the guide-plate Gris extended sufficien tly far beyond the point of the guide-block F and toward'the formerD to complete the crimping of the counter-stiffener.

The operating ends of the matrix-jaws e e are provided with downwardly-extendin g studs k k, which move in the curved guideways S S ofthe table A. The shape of said guideways is such 0 as to draw the said studs, and consequently the outer ends of the matrix-jaws, inward, so as to give a wiping motion in addition to the side pressure of the jaws. As said jaws are attached to each other solely by the hinge s, they are free to accommodate themselves to the motion given by said studs and gnideways. The lower ends of said studs are provided with buttons, which hold them from rising out of position. I00

The blank for the counter is first placed on protruding pins I I and aroundformer D, which then moves forward,causin g the matrixto close, and thereby shaping the sides of the counter. The crimping-jaws then close and crimp that part of the counter which is to be horizontal. The workman moves forward the next blank, and thus pushes the finished counter off the former D." It then falls through an openingin table A.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of aformer with springpressed pins protruding from its sides and a matrix arranged to force said pins inward.

2. The combination of a former with a matrix, guide-block, and springbearin g against the latter, said spring being adapted to yield only under excessive pressure, for the purpose set forth 3. A pair of reversely-curved jaws forming a'matrix, in combination with a triangularguide-block between the curved tails thereof,

and a former arranged to be pressed against 2 5 the said matrix in front of said guide-block, substantially as stated.

4. A pair of slotted crimping-jaws, in combination with fixed studs, a matrix to which said crimping-jaws are connected, and aformer, operating substantially as set forth.

5. A guide-plate forming a rear crimping device, in combination with crimping-jaws, a matrix, and a former, constructed and operating substantially as set forth.

6. In a machine for making boot and shoe counters, the formerD and its shank d, in combination with the plunger B, guide-standard A and cam 0, all substantially as set forth.

In testimony whereof I affix my signature 4o inpresence of two witnesses.
